New Lobby Release Model for 2.7+ / Zero-Downtime & Continuous Release
-
Lobby will be redeployed automatically every time there is a code update. This involves a restart and disconnecting everyone, except we can patch over that problem.
Namely we can spin up a second server to offload traffic, upgrade & restart the first server & then ship the traffic back.
A remaining issue is the client needs to automatically reconnect. Once that is done, this upgrade & restart of the server will potentially be seamless.
Of note, we can control which game client versions go to which lobbies. If we want to break compatibility, we can keep old servers running with the old versions.
Also notable is that we're moving to a place where releases are forced on us and are totally automated whenever any code changes.
